Major technology companies are bringing quantum computing commercialization plans forward, with some targeting deployment within three years as they address error correction and cryogenic infrastructure. IBM researchers demonstrated a spacetime probabilistic error cancellation technique on the superconducting IBM Aachen processor, combining error detection and mitigation and filtering out up to 65% of errors in advance. Intel CEO Lip-Bu Tan said the company is focused on error correction, applications and identifying customers, while describing GPUs, CPUs and quantum processors operating together. Intel Labs is developing higher-temperature Tunnel Falls silicon spin qubits, and IBM is pursuing modular cryogenic systems and an Andron quantum semiconductor foundry. Microsoft has set a 2029 target for its Majorana 2 chip, while Amazon's head of AI, Peter DeSantis, said commercially useful small quantum computers could emerge within five to seven years. U.S. government support includes executive orders signed by President Donald Trump, a planned $2.013 billion Commerce Department program for nine companies and a $100 million agreement with Quantinuum. The commercialization timetable will depend heavily on progress toward error-corrected systems and the infrastructure needed to operate them at extremely low temperatures.
